Greenhouse gases and global warming are severe issues for the living on earth and the main factor of these issues is the emission of harmful gases from fossil fuel or petroleum-used vehicles. Thus, the electric vehicle is proposed and commercialized to cut down the use of fossil fuel vehicles. However, the problem of battery cell imbalance of the electric vehicle leads to unsatisfactory and critical bad impacts on the battery lifespan and operating duration, in turn, reducing the public interest in electric vehicles. This paper discussed and proposed the solution to the cell unbalanced issue by utilizing the active cell balancing methods based on the Buck-Boost DC/DC Converter topologies with the integration of several closed-loop control systems and algorithms on the serially connected Lithium-Ion (Li-ion) battery cells in this work. The proposed cell balancing system is tested under a constant load test. Eventually, the proposed model managed to bring all the cells to a balanced state with a nearly similar State of Charge (SOC) for all the cells. MATLAB/Simulink is used for the development of this simulation model.

Several methods used for improving the transient response of a PFC converter involves modification of its inherent control loop. This study proposed an output-based method for the reduction of output disturbance during step loading, an approach that is independent from its inherent control. Through SIMPLIS simulation, the PFC converter was modelled first, then its compensator was designed to meet the stability requirement, and lastly, the proposed method was designed and modelled with its two main blocks, the load detection block, and the feedback voltage manipulation block. Through simulation results, the output undershoot is reduced by about 12.15% at worst input condition (180VAC) and during 10%-100% step load disturbance. Also, the output overshoot is reduced by about 7.92% at worst input condition (180VAC) and during 100% to 10% step load disturbance. The proposed method is also tested at several input conditions and output disturbances.

With the increasing popularity of electric vehicles (EVs), mileage anxiety and charging waiting caused by disorderly charging are the main constraints restricting the development of EVs. In this paper, we use stochastic geometric modeling and analysis of the vehicle road and location distribution network, combined with the residual mileage estimation model to estimate the remaining charge and charging probability of EVs at any location. The charging scheduling strategies of the first-come-first-served and same-moment low state of charge first-charged. The results show that the simulated MPLCP model can estimate the state of charge (SOC), drivers can make appropriate path planning, and achieve optimal charging options. The adopted charging strategy can reduce users' waiting time for charging at charging stations (CSs) and avoid congestion in CSs.

Based on the city data from 2003 to 2016, this paper evaluates the low-carbon level of Guangxi Province and cities. The entropy weight method is used to calculate the low-carbon level of each city, and then the FDA method and various curves are used to investigate the potential dynamic changes. The findings are as follows: (1) The low-carbon levels of cities in Guangxi are quite different, with Nanning (0.7739), Liuzhou (0.3936) and Guilin (0.3585) ranking the first three, Baise (0.1786), Hechi (0.1726) and Laibin (0.1726) (2) From the perspective of the dynamic characteristics of low-carbon development in different cities, the low-carbon level of most cities has an upward trend, but a few cities show a downward trend; (3) From the perspective of the dynamic characteristics of the overall low-carbon development, the overall low-carbon development level of Guangxi Province shows a trend of first falling and then increasing, and it still keeps an obvious upward trend at the end of the sample. This paper provides theoretical support for low-carbon development in Guangxi, which has important practical significance for realizing the goal of "peak carbon dioxide emissions, carbon neutral".

The existence of voltage range violations represents a challenge in low voltage grids with a high penetration of decentralized generation, storage capacities or electro-mobility. If grid expansion is to be avoided in the future, an extensive information exchange between the system’s components is required to provide an optimal energy supply and guarantee operating requirements. This can be studied in details by modelling the energy system components and the communication between them, which is one of the aims of the research project "Future Energy Laboratories". Highly integrated application scenarios for sample districts in Germany are simulated and thoroughly analysed during the project. For the detection and correction of voltage range violations at individual buses of a grid, an Open Source Grid Observer tool was developed and tested as a flexibility feature in a quasi-dynamic energy system simulation of a residential district. It allows a wide range of compatibility between various simulation scenarios, as it gives recommendations for power control at considered buses according to predefined flexibilities, such as the type of power (active or reactive), flexibility components (e.g. generation and storage) and injection increment. The corrections were calculated using two methods of the voltage sensitivity analysis theory. A comparison between the methods’ robustness, accuracy and calculation speed is presented, being important performance factors to be considered in this kind of simulations. The functionality of the tool is demonstrated in scenarios with temporary peak loads from electric vehicle charging or a high share of distributed photovoltaic power generation.
